Hydrangea paniculata prefers a sunny or semi shaded position, with shelter from cold, drying winds. Grow hydrangea plants in any non alkaline, fertile, moist soil. Improve the soil prior to planting by adding with plenty of well rotted manure or garden compost, ensuring that it is mixed in thoroughly and deeply.
To enhance flowering prune hard in early spring, cutting back the previous season's shoots to within a few buds of the permanent, woody framework of the plant.
